I once attended a "watch hour" service at a Pentecostal church with an old girlfriend. They didn't claim any martial arts powers but they did claim all kinds of other ****; world was ending that night and the only people to see heaven were members of their particular sect. The preacher then stated that he knew there were non-believing interlopers among them and that the wrath these people would receive would be severe. People worked themselves into a god-frenzy and started running around, speaking in tongues, and flopping around on the floor like fish out of water, all the while the preacher was screaming about Jesus being on his way to lay down his vengeance. I wasn't sure what to make out of it, but i promptly got the **** out of there. It was terrifying.

Now lovely Lucifer, in hell so stark
King, and lord of sin and pride
With some mist his wits make dark.
He send thee grace to be thy guide
